internal cylindricalworkpiecevertical

Overview
Meccanodora cage grinding machines perform external, internal and window grinding for production of ball cages used in CV joints and ball bearings. Available as single-spindle, double-spindle or multi-spindle configurations, these machines integrate handling and loading systems for fast, repeatable and automated part processing.

Key capabilities

• External grinding (OD)
• Internal grinding (ID)
• Window grinding (cage windows)
• Single-spindle and multi-spindle configurations (including double-spindle and six-spindle solutions)
• Built-in automated loading/unloading and handling systems for short setup times
• Dry-grinding variants available as alternative to wet machining

Industries

• Automotive OEMs and suppliers — production solutions for drive-shaft and joint components
• Truck manufacturers and suppliers — grinding technology for commercial vehicle parts
• E-mobility — series production of high-precision drive components

Advantages

• Flexibility: supports high-precision OD, ID and window grinding across configurations
• Precision dressing: diamond or profile-roll dressing ensures accurate profile control
• Ergonomics and safety: full enclosure designs for operator-friendly use
• High automation: integrated loader/unloader for automatic part introduction and efficient changeover

Applications & Typical Use Cases

• Ball cage machining: single- and multi-spindle grinding and milling of cage windows (4, 6, 8, 10, 12 windows), including simultaneous multi-window machining
• Outer-diameter grinding: high-precision OD grinding of ball cages with conventional grinding wheels
• Inner-diameter grinding: high-precision single-spindle ID grinding
• Joint hub cage OD grinding: fully automatic loading/unloading and low-maintenance designs for high throughput

Machine types (examples)

• Meccanodora 1309/CNC — CNC external grinding machine for OD grinding (example single-spindle OD grinding)
• Meccanodora 4200-F/CNC — cage milling machine for single-spindle machining of multiple cage windows
• Meccanodora RI-0G/CNC — single-spindle high-precision ID grinding with built-in loader/unloader
• Meccanodora RF6-2P/CNC — six-spindle CNC internal grinding machine for simultaneous grinding of six cage windows
• Meccanodora Vertical Combi — combined machine for OD and ID grinding with automatic loading/unloading

Notes
Models can be supplied with full enclosure and configured for dry or wet machining depending on production needs. Dressing solutions (diamond or profile roll) are used to guarantee dressing precision and profile control.
